PERM UTATION-PADLOCK.

SPECIFICATION forming part of Letters Patent No. 534,534, dated February19, 1895.

Application filed August 31, 1894. Serial No. 521,824. (No model.) i

To all whom it may concern.-

Be it known that I, HERMANN WAGNER, of Quinnesec, in the county ofDickinson and State of Michigan, have invented a new and usefulImprovement in Locks, of which the following is a full, clear, and exactdescription.

My invention relates to an improvement in looks, and particularly to animprovement in looks of the combination type and adapted as padlocks,trunk and desk looks, or for similar purposes.

The object of the invention is to produce a lock of the above characterwhich will be exceedingly simple, durable and economic, and which willlikewise be exceedingly safe, being provided with a combination whichwhen set will require considerable skill to discover if the combinationbe not known.

The invention consists in the novel con-" 7 struction and combination ofthe several parts, as will behereinafter fully set forth, and pointedout in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a perspective view of the lock viewed from the front. Fig. 2is a central longitudinal vertical section through the lock. Fig. 3 is aperspective view of the lock casing with the back plate removed. Fig. 4is a perspective view of the back plate of the casing. Fig. 5 is avertical section taken through the casing,practica1lyon theline 55 ofFig. 3, the back plate of the casing being included in the section. Fig.6 is a similar section taken essentially on the line 6-6 of Fig. 3 theback plate of the casing being included in the section. Fig. 7 is aperspective View of the keeper of the lock. Fig. 8 is a perspective viewof one of the locking slides; and Fig. 9 is aperspective View of thecombination slide forming a portion of the locking slide.

In carrying out the invention the casing A may be made in any desiredshape, but ordinarily it is somewhat rectangular in general form, asshown in Fig. 3. The said casing is provided with a solid bottom 10,closed sides 10, a top 1O integral with or firmly attached to the sides,and a front 12, provided with a preferably central opening 12 extendingthrough from top to bottom. The back of the casing is open, and in thebottom portion of the back a longitudinal recess 11 is produced, in

which pins 11 are usually placed. At the top ofthe casing a bar 13 isformed at the front,

made integral with the top and front face of the casing. This barcrosses the opening 12 in the front of the casing, and at suitable'bination.

In the central portion of the top of the easing an opening 15 is madewhich is usually square, and in the central inner edge of the top bar 13and partitions 14, corresponding recesses 16 are formed, the recessesand openings being in vertical alignment. In the arrangement of thepartitions 14 the uppermost one is the widest, the partitions becomingnarrower as they approach the bottom. A second opening 17, is likewisemade in the top of the casing at one side of the opening 15. I

The back plate 18 of the casing may be and usually is provided upon itsinner face with partitions which correspond to those in the casing, butthey do not meet the casing partitions when said plate is in place. Theback plate is likewise provided with apertures in the bottom portionthereof to receive the pins 11" in the back lower portion of the casing,

and an aperture 19, is usually made in the top of the back plate nearone end, which when the said plate is in position in the easing willregister with a similar aperture 19 made in-the top of.the casing,and bypassing a screw into these two apertures, as shown in Fig. 5, the backplate is securely locked to place.

The keeper B is illustrated in Fig. 7. This keeper comprises a shackle20, terminating at one end in a reduced square section 21, adapted toenter the opening 17 in the casing, which is of like contour. Theopposite end of the shackle is provided with an inwardly extending barmember 22, and from the inner extremity of this bar member a tongue 23,is downwardly projected, terminating at its lower end in a lip 23 at aright angle to the tongue proper. t

In the manipulation of the shackle the tongue and its lip are passeddown through the opening 15 in the casing and the recesses 16 in thepartitions and between the abutments or guiding lugs (see Fig. 6) of theback 18 until the lip shall rest upon the bottom of the casing, as shownin Fig. 2. The bar member 22, will then rest upon the top of the easingand will cover the screw which has been placed in the aperture 19 andutilized to secure the plate 1 8 in position, and the reduced section 21of the shackle will have entered the casing opening 17.

In connection with the shackle and the easing, a series of lockingslides C is employed. In the drawings three of these slides areillustrated as being used, andthree scales are produced upon the frontof the casing, two partitions only being located within the same. Theselocking slides .are angular in cross section, comprising an upper orhead member 24 and shank members 25 which are flush with one side edgeof the head, extending downwardly therefrom. Both the head and shankmembers of a slide are provided with an opening 26, extending from topto bottom, the opening being of sufficient size and of such shape as topermit the passage through the slide of the tongue 23 of the keeper andits lip 23. A series of apertures 27 is produced longitudinally in theouter face of the head section of each lockingslide. In connection witheach locking slide a combination slide 28 is employed. This combinationslide is adapted for engagement with the apertured face of the lockingslide, and is provided with a pin 29 which extends beyond both sides ofthe combination slide,being adapted to enter any one of the apertures 27in the locking slide. The shank members of the locking slides aregraduated in length. One slide, the longer one, has its head memberplaced between the uppermost partition 14 and the top bar 13, being heldto slide in the ways thus provided, and its shank members (see Fig. 8)extend downward and abut the lip 23 of the keeper tongue. The nextshorter locking slide is placed between the lower partition 14 and theupper one, having sliding movement in this position; and the lower endof this shank is in advance of theupper locking slide and likewiseengages with the lip of the keeper tongue, while the lower and shorterlocking slide is held to travel between the lowermost partition 14: andthe bottom of the casing, its shank resting upon the latter, while itshead rests upon the lip of the keeper tongue. This lower slide has theapertures 27 produced in the face with which its shank is connected,since it is placed in just a reverse position to the other slides, asclearly shown in Fi 2.

534.53&

A combination slide is placed in engagement with the apertured portionof each locking slide prior to the locking slides being placed inposition in the casing, being so placed when the plate 18 is removedfrom the casing; and the pins 29 of the combination slide are thenplaced in an aperture of a looking slide, the outer face of thecombination slides being flush with the scale surfaces appearing at theopening 12 in the front of the casing.

When all of the locking slides have been adjusted in the casing in amanner to bring their openings 26 in registry, and likewise in registrywith the tongue and lip of the keeper, the latter may be drawn out fromthe casing, and only then. After, however, the keeper has been placed inthe casing in proper position and the slides have been shifted in acareless manner, the keeper cannot be with drawn until the combinationis formed or known, and the combination is obtained by placing the pinof each combination slide in for example a difiereut aperture of itslooking slide, and noting the numbers on the scales to which the pinsmust be moved to bring the apertures 26 of diiterent slides in registryover the tongue of the keeper to permil; of the withdrawal of thelatter. The combination may be changed at any time by removing the plate18 from the lock.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a lock of the padlock type, a casing having aseries of slideways and provided with openings in the slideways and inthe cas ing proper, a keeper provided with a tongue, said tongue beingadapted to enter said openings within the casing, and locking slideshaving movement in the ways in the casing and locking engagement withthe tongue, each slide being provided with releasing openings for thetongue, and a combination slide atljustably carried by each lockingslide, as and for the purpose set forth. i
